Carried by the packing box arrangement 23 is-a shield or splash guard enclosing the upper end of hub 21 to prevent any oil etc., which might be in the recess 24, from splashing onto the glass being surfaced. The splash guard 25 also supports the main abrasive supply pipe 26." Secured to the hubf21 beneath the key,

22 is a lower splash guard 27 which surrounds the annular upstanding flange 19 formed on the cover plate 18 whereby to prevent any abrasive from getting into the socket or recess 17 and thereby clogging up or otherwise interfering'with the operation of the ap- .paratus.

Formed integral with the mainfrunner casting lOfand surrounding the housing 16 is an annular trough 28 for receiving the mixture of abrasive and water, which is to be used and which is supplied to the cavity 13 through the openings 15 in plate14. This mixture of abrasive and; water is initially fed into the trough 28 through the supply pipe. 26 carried by the upper splash guard 25.

The lower end of the hub 21 is received within the socket 17 and is provided with three laterally projecting portions or arms 29, 30'and 31.up0n each of which rests a compression spring 32, the upper end thereof bearing against a spring seat formed on the under face ofthe cover plate 18.

The hub 21 is also providedsomewhat high er up'with three laterally projecting driving arms 33, 34 and 35, these arms being arranged alternately withthe spring supporting arms 29, 3O and31 as shown in Fig. 3. Each of the driving arms 33, 34 and 35 is provided with a preferably bronze roll 36 which contacts with a preferably steel wear-plate 37 bolted to the inside of the housing 16. The rolls 36 serve to hold the runner or grinder head centrally located.

Projecting downwardly from the underface of the cover plate 18 are six lugs 38, these'lugs being arrangedbetween the spring supporting and driving arms above described as clearly shown in Fig. 3. The lugs 38 rest against bosses 39 formed on the bottom of the Y grinder recess17, said lugs being provided upon their faceswhich are adjacent the driving arms withpreferably bronze wearing strips 40 with whichthe driving arms con tact. 7

In the operation of the invention, and upon rotation of the runner spindle 7 and hub 21, the driving arms 33, 34 and 35 engaging the lugs 38 will serve to impart a rotary movement to thegrinder head or runner. Since the driving arms are positioned between the lugs, the runner maybe driven either in a clockwise or a counter-clockwise direction. The sheets of glass 41 to be surfaced are adapted to be supported upon the uppersurfaces of a series of .tables 42 mounted upon tracks 43, these tables servingt'o carry the glass sheets beneath the grinder heads or runners of a series of surfacing machines of the type set forth above. Due to the particular manner in which the runner is secured to its spindle, the said runner will be permitted a'limited and variable amount ofrocking movement. Also, the runner will further be permitted a certain amount of vertical movement as a whole'relative to the spindle since there is a certain amount of clearance between the bottom of the hub 21and plate 14. With the construction shown, the runner only is-yieldably supported by the compres sion springs 32 so that when the whole weight of the runner isnot resting on the glass, a

part of its weight is taken up by these springs. v For the purpose of supporting the grinding machine, there is provided a hanger j bracket 44, the upper end thereof resting upon and being secured to a horizontal-JI- beam 45 while the lower end bearsagainst or 'is secured to a lower horizontal I-beam46. "The hanger bracket 44'is providedadjacent itsupper end with spaced vertical cylinders or sleeves 47 and at its lower end with aplurality of bearings 48. v

Carried at the upper end of the casing 6 is a pair of oppositely disposed plungers 49 which are slidably received within the cylinders or sleeves 47 while extending from the casing adjacent its lower end areaplurality of arms carrying vertical pins 50 slidably received Within the bearings 48. The grinding machine may be readily removed from the hanger bracket by simply liftingthe same until the plungers 49 and pins 50 are disengaged from the cylinders 47 and bearings 48 respectively. I

In order to raise and lower the'grinding machine, there is carried by each plunger 49 a depending adjusting screw 52 threaded 5 through a worm gear 53 which is in constant 1 mesh with a Worm 54 mounted upon shaft 55.. Upon rotation of the shaft 55, the worm gears 53 can be rotated in the desired direction to either raise or lower the grinding machine and the said shafts can be connected together,

if desired, in such a manner that both plung-v 1 ers can be simultaneously raised or lowered so that both sides of the grinding machine may be raised or lowered an equal distance.

It is to be understood that the form of the invention herewith shown and described is to be taken as the preferred embodiment of the same, and that various changes in the shape, size and arrangement ofparts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.
